Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a valve body fixing device for valve processing. Background Technology

[0002] As a key control component in industrial pipeline systems, the quality of valve manufacturing directly affects the sealing performance and service life of fluid control systems. During valve manufacturing, the valve body, as a core component, requires multiple precision machining processes, including end face milling, flange hole machining, and sealing surface turning. According to CN119347702A, a fixing fixture and processing method for machining marine valve bodies are disclosed. This technology discloses "a fixing fixture and processing method for machining marine valve bodies, which relates to the field of fixing fixture equipment technology. The fixing fixture includes a valve body machining support. Both sides of the top of the valve body machining support are provided with valve body machining flipping drive components. Using the valve body machining support as a carrier, and with valve body machining flipping drive components on both sides of the support, the clamping jaws can flip the valve body according to the processing needs after clamping the valve body, so that the valve body machining angle can be changed. By using an electric push rod to move the clamping jaws, the clamping jaws can clamp valve bodies of different lengths and sizes." The technical solution has the following effects: "The fixing fixture can increase the application range of valve bodies of different sizes. The clamping jaws can clamp the outer surface of the valve body or penetrate into the interior of the valve body for expansion clamping. It not only achieves the effect of not obstructing the processing window, but also can clamp small-sized valve bodies." In the current valve processing, traditional fixing devices cannot simultaneously meet the processing requirements of valve bodies in different installation positions. When it is necessary to process cylindrical valve bodies facing forward and backward and valve bodies with planar reference facing left and right, different special fixtures must be used for clamping. This not only increases equipment investment and changeover time, but also causes the processing flow to be interrupted, seriously affecting the continuity of production. Utility Model Content

It adopts a dual-station design, which can alternately fix valve bodies in different positions for sequential processing. The optimized layout avoids interference and achieves efficient continuous production, ensuring both accuracy and space saving. It is particularly suitable for multi-process valve body processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a valve body fixing device for valve processing, comprising a fixing mechanism for positioning a first valve body and a second valve body, the fixing mechanism comprising: An adjustment assembly is mounted on the machining table and used to adjust the angle of the first and second valve bodies after positioning. The tooling assembly includes a base mounted on the adjustment assembly. First clamping cylinders are installed at the front and rear ends of the top left side and the front and rear ends of the top middle left side of the base, which are used to fix the first valve body when it is placed in the front-rear orientation. Second clamping cylinders are installed at the front and rear ends of the top right side and the front and rear ends of the top middle right side of the base, which are used to fix the second valve body when it is placed in the left-right orientation. The mounting component is set on the adjustment component and is used to fix the tooling component on the adjustment component.

[0005] Preferably, the mounting assembly further includes a mounting base disposed on the adjusting assembly.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a valve body fixing device for valve processing, including a fixing mechanism 1 for positioning a first valve body 2 and a second valve body 3, the fixing mechanism 1 including: Adjustment component 11 is installed on the processing table and is used to adjust the angle of the first valve body 2 and the second valve body 3 after positioning. The tooling assembly 12 includes a base 121 mounted on the adjustment assembly 11. First clamping cylinders 122 are installed at the front and rear ends of the top left side and the front and rear ends of the top middle left side of the base 121, and are used to fix the first valve body 2 when it is placed in the front and rear orientation. Second clamping cylinders 123 are installed at the front and rear ends of the top right side and the front and rear ends of the top middle right side of the base 121, and are used to fix the second valve body 3 when it is placed in the left and right orientation. Mounting component 13 is mounted on adjusting component 11 and is used to fix tooling component 12 on adjusting component 11.

[0016] In this embodiment, the tooling assembly 12 adopts a dual-station asymmetrical layout. The first clamping cylinder 122 is arranged in a front-to-back orientation on the left side of the base 121, and its clamping end adopts an arc-shaped jaw structure, specifically used to clamp the cylindrical outer surface of the first valve body 2 placed in a front-to-back orientation. The second clamping cylinder 123 is arranged in a left-to-right orientation on the right side of the base 121, and its clamping end adopts a planar jaw structure, specifically adapted to the planar reference surface of the second valve body 3 placed in a left-to-right orientation. By adjusting the coordinated control of the assembly 11, the first valve body 2 can be kept in a front-to-back orientation. The end face is machined in a fixed state. After completion, the station is adjusted by adjusting component 11 so that the second valve body 3 is rotated to a fixed left-right orientation for side machining. The asymmetrical arrangement of the two sets of first clamping cylinders 122 and second clamping cylinders 123 not only ensures their optimal clamping positions, but also avoids machining interference through reasonable space planning. This alternating machining mode realizes efficient sequential machining of valve bodies in two different orientations, which saves equipment space and significantly improves machining efficiency by optimizing the process flow. It is particularly suitable for the continuous machining needs of multi-process valve bodies.

[0017] Specifically, the mounting assembly 13 also includes a mounting base 131 disposed on the adjusting assembly 11. Threaded rods 132 are rotatably mounted on both ends of the mounting base 131. Nuts 133 are threaded onto the outer walls of both ends of the threaded rods 132. A mounting plate 134 is fixed to the bottom of the base 121. Extensions 135 are fixed to both ends of the mounting plate 134. Grooves 136 are provided on both sides of the outer ends of the extensions 135.

[0018] In this embodiment, this modular installation method not only enables quick assembly and disassembly of the tooling component 12 and the adjustment component 11, but also facilitates equipment maintenance and tooling replacement.

[0019] Specifically, the tooling assembly 12 also includes a positioning head 125 fixed to the top of the base 121 and used for positioning the valve body.

[0020] In this embodiment, the positioning head 125 facilitates the quick pre-positioning of the first valve body 2 and the second valve body 3 on the base 121.

[0021] Specifically, the tooling assembly 12 also includes a pipeline system 124 that connects the first clamping cylinder 122 and the second clamping cylinder 123 and is used to realize the linkage control between the two.

[0022] In this embodiment, the air inlet chamber and exhaust chamber of the first clamping cylinder 122 and the second clamping cylinder 123 are connected in parallel through a high-strength polyurethane air pipe, and a diversion control valve is set on the main pipeline to ensure balanced air pressure distribution; so that the first clamping cylinder 122 and the second clamping cylinder 123 can achieve synchronous operation and maintain a consistent clamping force when clamping the first valve body 2 and the second valve body 3.

[0023] Specifically, the adjustment assembly 11 includes a secondary spindle frame 112 rotatably mounted between the two ends of the main spindle frame 111. A first servo motor 113 is mounted on the outer wall of the main spindle frame 111 and is used to drive the secondary spindle frame 112. A second servo motor 114 is mounted on the bottom of the secondary spindle frame 112 and is used to drive the mounting base 131.

[0024] In this embodiment, the main spindle frame 111 drives the secondary spindle frame 112 to rotate horizontally via the first servo motor 113, while the second servo motor 114 at the bottom of the secondary spindle frame 112 drives the mounting base 131 to achieve angle adjustment in the vertical plane; thus enabling the first valve body 2 and the second valve body 3 to achieve precise positioning at any angle during the processing, meeting the processing requirements of complex processing surfaces.

[0025] Specifically, the clamping ends of the first clamping cylinder 122 and the second clamping cylinder 123 are provided with anti-slip textures, and the shape of the clamping surface is adapted to the outer contour of the valve body.

[0026] In this embodiment, even when subjected to cutting forces during processing, the first valve body 2 and the second valve body 3 will not be displaced or rotated, effectively preventing accuracy deviations caused by processing vibrations.

[0027] The working principle and usage process of this utility model are as follows: First, the tooling assembly 12 adopts a dual-station asymmetrical layout. The first clamping cylinder 122 is arranged in a front-to-back orientation on the left side of the base 121, and its clamping end adopts an arc-shaped claw structure, specifically used to clamp the cylindrical outer surface of the first valve body 2 placed in a front-to-back orientation. The second clamping cylinder 123 is arranged in a left-to-right orientation on the right side of the base 121, and its clamping end adopts a planar claw structure, specifically adapted to the planar reference surface of the second valve body 3 placed in a left-to-right orientation. By adjusting the coordinated control of the assembly 11, the first valve body 2 can be kept in place first. The end face is machined in a fixed front-to-back orientation. After completion, the work position is adjusted by adjusting component 11 so that the second valve body 3 is rotated to a fixed left-to-right orientation for side machining. The asymmetrical arrangement of the two sets of first clamping cylinders 122 and second clamping cylinders 123 not only ensures their optimal clamping positions, but also avoids machining interference through reasonable space planning. This alternating machining mode realizes efficient sequential machining of valve bodies in two different orientations, which saves equipment space and significantly improves machining efficiency by optimizing the process flow. It is particularly suitable for the continuous machining needs of multi-process valve bodies. Furthermore, the main spindle 111 drives the secondary spindle 112 to rotate horizontally via the first servo motor 113, while the second servo motor 114 at the bottom of the secondary spindle 112 drives the mounting base 131 to achieve angle adjustment in the vertical plane; thus enabling the first valve body 2 and the second valve body 3 to achieve precise positioning at any angle during the processing, meeting the processing requirements of complex processing surfaces.
